Process	Flame cutting
	A traditional method for cutting metals, especially thick plates e.g. for shipbuilding. Most geometries can be made. The major drawback is the heat introduced into the material and the following thermal distorsions. A high temperature flame (about 3000 c) made from a mixture of fuel gas (e.g. acetylene) and pure oxygen heat the material in the cutting region resulting in a combination of rapid oxydation and melting. The oxides / the melt is blown away by the gas pressure.
Danish Name	Flammeskæring
Category	Reducing processes, Cutting
Materials	Metals
Typical products	Shipplate
Competing processes	Plasma cutting Angle grinder
Price notes	Fairly low cost equipment. Variable cost comes from consumed gas and oxygen and correction work needed after thermal distorsions.
Environmen- tal notes	Use: Working environment problems from undesired gasses and intense light require that ventilation and protection glasses must be used.
Keywords	Sheet metal cutting Plane surfaces Cylindrical surfaces
